4 claims. (ci. 12e-9o) My invention relates to wall furnaces, more particularly a small furnace to be placed in the wall between two rooms for heating either or both rooms, and the objects of my invention are:

First, to provide a furnace of this class which may be placed in an eight inch partition for heating the adjoining rooms on opposite sides of said partition or either of said rooms;

Second, to provide a furnace of this class in which the side of the partition may be plastered over and all of the exposed area is the inlet and outlet grills for taking in the cold air and providing an exit for the outlet of the heated air;

Third, to provide a furnace of this class with means for dei'lecting the heated air to either of the rooms on the opposite sides of the partition;

Fourth, to provide a furnace of this class which provides means for taking air from the outside and passing it into the room with the heated air for supplying fresh air to the rooms;

Fifth, to provide a furnace of this class which may be placed between two studs of the partition and is insulated therefrom;

Sixth, to provide a novel heater casing for furnaces of this class;

Seventh, to provide a novel circulating air means for heaters of this class;

Eighth, to provide novel venting means for furnaces of this class which diverts back drafts from the flue;

Ninth, to provide novel heat distributing means for wall furnaces;

Tenth, to provide a novelly constructed furnace of this class which is very simple and economical of construction, easy to install, efficient in its action, and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination, and arrangement of parts and portions as will behereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The heater casing l heat distributing casing 2, vent 3, burner 4, air conducting casing 5, outer casing 6, cold air inlet grills 1 and 8, hot air outlet grills 9 and l0, asbestos lining H, shiftable deflectbr l2, stationary deflectors I2b and I 2c, partitions i3 and I4, tile vent i5, and shield I6 constitute the principal parts of my wall furnace.

This wall furnace is positioned between two studding S which are substantially two-by-eights and with a header H at the top, and supported above the floor by means of cross beams B which form the support at the bottom and are positioned on the oor F. Mounted in this space between the studding, header, and beams is a metallic casing 6 which is closed on all sides but is provided on each side at the bottom with open spaces over which are mounted the cold air inlet grills 'l and 8 30 which are secured to this casing over said openings; also at the upper side are provided openings at opposite sides over which are secured the heated air outlet grills 9 and I0. Positioned between the outer side of this casing 6 and thestudding and 35 heater is an asbestos lining Il, which protects the studding and other woodwork from the metal casing. Also on the opposite sides between the heated air grills 9 and l0 and the cold air grills 1 and 8 is provided asbestos lining Il. Positionedon the 40 outside of this asbestos lining Il is plaster supporting wire W over which is provided a plaster covering P so that the sides of the heater are covered at the exterior with plaster so that nothing shows except the grills in the upper and lower sides of the furnace as shown best in Fig. 6 of the drawings.

Mounted centrally in the casing 6 and directly over a burner 4 is thev heater casing l which is hollow and rectangular and extends substantially one-half the heighth of the furnace. 'I'his casing I is open at its upper end la except for the short ends Ib. Below the end la is a baille member lc which is shaped as shown best in Fig. 10 ofthe drawings leaving two opposed open spaces ld and lso Ie for the heated air to pass through and be circulated upwardly. Below this baille member Ic is another baille member If shaped as shown best in Fig. 11 of the drawings with open spaces on opposite sides from the baille Ic as disclosed by Ig and Ih, and below the baille member If is another baille member Ii and this baille member is shaped as shown best in Fig. l2 with two openings Ii and Ik. v

Superposed above the heater casing I and extending downwardly around the upper side thereof is heat distributing casing 2 which is boxshaped and open at its lower side so that the edge extends down over the casing I a short distance. It is provided at its upper side with a central oriiice 2a from which extends upwardly a vent 3 which is cylindrical in form and provided over its upper end is a conical cover 3a and leaving an open space 3b above said vent immediately below this cover 3a. This heat distributing casing 2 is provided with a transversely positioned baille member 2f shaped as shown best in Fig. '7 of the drawings and leaving two openings 2g and 2h and below this baiileis another baille 2i which is provided with two openings 21 and 2k. Thus it will be noted that the heat from the burner 4 is baiiled in a zigzag course to the oriiice Ib; then it is again baiiied in a zigzag course to the vent 3, and then passes upwardly through the flue I5 which is composed of tile or similar subject matterl which is spaced from the header H as shown by space lia and provided by a cover plate lib. Positioned in the lower end of the vent I5 and surrounding the upper end of the vent 3 is a conducting member I1 which conducts the exhaust from the burner upwardly into the ue I5. Positioned on opposite sides of the vent 3 and secured at its ends and to the vent 3 is a deector I2b which is shaped as shown best in Figs. 2 and 4 oi the drawings consisting of an upper straight portion I2a, two angular portions |217 and I2c which connect near the middle of the member I 2a in spaced relation therefrom and pivotally mounted at the lower extremity is a downwardly extending pendant portion I2. 'I'his member I2 is adapted to be shifted on its pivotal axis to position shown by dash lines in Fig. 2 of the drawings or may be shifted in the opposite direction, and is for the purpose of directing the heat from around the heater casing I and heat distributing casing 2 to a room at either side of the partition in which the furnace is mounted. However, when the pendant I2 extends straight down as shown by solid lines, the heat then is distributed in both directions to the roomson the opposite sides, it being noted that 'the pendant member I2 is adapted to come in substantial alignment with the lower edge of the grilles 9 or III which conilne the air passing upwardly through the inlet grilles 'l and 3 upwardly along the heater casing and heat distributing casing and upwardly so that it passes out through the outlet grilles 9 and I0 regulated by the shiftable deiiector I2. Interposed between the partition I3 and the outer walls of the heater casing I and the heat distributing casing 2 are partitions I4 which tend to further distribute the air passing upwardly and adds to the eillciency of the heating surface by conduction from the heater casing and heat distributing casing.

Positioned between the ends of the casing 3 and the heater casing I are upwardly extending offset supporting members I8 and the lower side of which forms the iioor Ila of the furnace mesma mountedontheupperbeamB. Itwill be here noted that thenoorandbeamnaxecut away to provide passages C for cold air coming up from under the door which passes upwardly betweentheendslandcasingiandpassesout through the upper openings in the grilles 3 and Il into the rooms to supply fresh air inthe rooms which is heated on its way upwardly. l

The shield Il extends upwardly between the grilles 'l and l to the lower side of the heater. casing I and serves to prevent drafts through from one of the grilles 'I to the grille l.

Though I have shown and described a particular construction, combination, and arrangement of parts and portions, I do not wish to be limited to this particular construction. combination. and arrangement. but desire to include in the scope of my invention the construction, combination, and arrangement substantially as set forth in the appended claims.
